Abstract

A note ofurgencycan sometimes be heard, even in otherwise unhurried writers, when they ask for a justification of morality. Unless the ethical life, or morality, can be justified by philosophy, we shall be open to relativism, amoralism, and disorder. As they often put it: when an amoralist calls ethical considerations in doubt, and suggests that there is no reason to follow the requirements of morality,what can we say to him?Why should one be moral? This question is nearly as old as the discipline of moral philosophy itself; it has been troubling ethicists ever since Glaucon challenged Socrates to disprove that “the life of the unjust man is much better than that of the just.” To find an answer to the question of why one should be moral has been taken to be one of the most fundamental tasks of moral philosophy. And even a casual survey of the history of ethics will reveal that there are many ways of trying to answer the question.
